Introduction to Multichain
Multichain is a pioneering cross-chain router protocol designed to serve as the foundational infrastructure for Web3 interoperability. Originally launched as Anyswap in July 2020, it rebranded to Multichain to reflect its expanded vision of enabling seamless cross-chain interactions for tokens, NFTs, and smart contract calls. With support for 1,600+ assets across 30+ blockchains, Multichain combines speed, security, and scalability to empower decentralized applications (dApps).
Key Features of Multichain
1. Cross-Chain Router Protocol (CRP)
- Facilitates arbitrary cross-chain interactions beyond token transfers, including NFTs and contract calls (
anyCall). - Supports EVM chains, Cosmos, Polkadot parachains, and non-EVM networks like Bitcoin.
2. Secure Multi-Party Computation (SMPC) Network
- A decentralized node network collectively signs transactions, eliminating single points of failure.
- Nodes are operated by independent entities, incentivized to maintain protocol integrity.
3. Optimized User Experience
- 4x faster than Anyswap with lower fees.
- 1:1 no-slippage swaps for cost-efficient transfers.
4. Unparalleled Connectivity
- Bridges native assets, wrapped tokens, and hybrid assets via liquidity pools or mint/burn mechanisms.
How Multichain Works
Bridge Design
Two-Chain Bridges
Uses lock-and-mint mechanism:
- Assets locked in SMPC-managed smart contracts on the source chain.
- Equivalent wrapped tokens minted on the destination chain.
Multi-Chain Router
- Native Assets: Relies on liquidity pools (e.g., USDC).
- Bridged Assets: Unlimited supply via
AnyswapV5ERC20.solcontracts. - Hybrid Assets: Mix of native and wrapped tokens (e.g., FTM on Fantom vs. Cronos).

Security and Risks
Security Measures
- Audits: Conducted by TrailOfBits, PeckShield, and SlowMist.
- Bug Bounty: Up to $1M rewards for vulnerability reports.
- Open-Source Code: Enhances transparency and decentralization.
Potential Risks
- Node Collusion: Unlikely but theoretically possible in SMPC networks.
- Smart Contract Vulnerabilities: Historical issues patched promptly (e.g., 2022 liquidity pool bug).
Supported Chains and Assets
Multichain supports major blockchains, including:
- Ethereum, BSC, Polygon
- Cosmos, Polkadot, Terra
- Bitcoin, Litecoin
Total Value Locked (TVL): Over $5B.
FAQ Section
Q: How does Multichain differ from other bridges?
A: Multichain’s arbitrary message passing (anyCall) and NFT support set it apart, enabling complex cross-chain dApp functionalities.
Q: Is Multichain secure?
A: Yes—its SMPC network, audits, and bounty program mitigate risks, though users must trust node operators.
Q: What chains are supported?
A: 30+ chains, including EVM, Cosmos, and non-EVM networks.
Conclusion
Multichain’s robust architecture positions it as a leader in cross-chain interoperability. By integrating with platforms like LI.FI, it accelerates the transition to a multi-chain Web3 ecosystem.
